Description
Coo Erhard is a major and core member of the Black Gema Gema Gang, serving as the group's physician despite being only 13 years old. He debuted in the *Di Gi Charat Christmas Special* and plays a significant role in the *Leave it to Piyoko!* series.
Physically, Coo has short dirty blonde hair and reddish-brown eyes. His distinctive canine traits include a dog tail, a dog cap, and occasional dog-like behaviors such as catching airborne food in his mouth.
Coo shares a close history with the gang's leader, Piyoko, as her childhood friend and closest confidant. Despite Piyoko being 8 years old and mistakenly believing herself older than Coo, he holds the "brother" role within the gang's familial structure.
His personality blends pragmatic skepticism with underlying loyalty. Coo frequently voices doubts about Piyoko's plans when they seem ill-conceived, acting as the group's reality check. This critical stance coexists with unwavering support for Piyoko and deep concern for her well-being. Generally calm and level-headed, he can display moments of brattiness or selfishness, especially when bossed around.
As part of the PKO unit alongside Rik Heisenberg and Ky Schweitzer, Coo functions as one of Piyoko's three primary caretakers under the Black Gema Gema umbrella. The unit undertakes missions primarily focused on antagonizing Dejiko, though they often encounter setbacks or distractions.
